Support for the US mission in Afghanistan has slipped to a new low, with 44 percent of Americans now saying the war there has been worth the cost, according to a recently released poll.

Amid mounting divisiveness over what was once one of President Barack Obama’s top foreign policy issues, the poll by The Washington Post and ABC News also showed ratings for how he has handled the mission there eroding, to 45 percent approving of how he is dealing with Afghanistan and 47 disapproving, compared to 63 percent approval last year.

The numbers come as Obama grapples with whether to send more US troops to Afghanistan to boost the fight against a growing Taliban-led insurgency, just a week after a stopover at a US military base in Alaska at the start of his Asia trip when he told US troops he will get “public support back home” for the mission.

Only 44 percent now say the war in Afghanistan has been worth fighting — the fewest since early 2007 — and 52 percent say it has not, up 13 points from its low of last December, the news outlets’ polling divisions said.
